QuickShootPro will ensure you never miss out on another photo opportunity just because you were waiting for a camera app to launch. It enables you to capture photos and videos quickly. You can double tap icons on your home screen to take images, and triple tap for video recording. You can even double tap the lock screen grabber to capture an image.

A lot of handy functionality like an options window (to change settings like flash, camera device, HDR, etc.) without going into Settings.app, activator actions for both video and image capture, the ability to set custom app icons to double tap, and more little things that I’ll leave to you to find out have been added.

Note
I've had quite a few requests to disable the shutter sound in that is played when an image is captured. I'd like to address this once and for all: It won't be done. The sound is not intentionally played by me, iOS is engineered in that way. It is required by law in many countries for a shutter sound to be played when a photo is being captured, and is not worth the effort to have to check up every country's (oftentimes obscure) laws, when this sound can be disabled by simply turning on silent mode, at least as far as iPhones and iPads go.
